METHODS: Here, we report a case of a 66-year-old female with a history of bilateral ADPKD and urinary tract infection admitted to our hospital due to right flank pain, feeble, and low-grade fever. Contrast-enhanced ultrasound revealed a malignant mass of the right kidney suspected to be a cystic renal cell carcinoma with polycystic kidney disease. In addition, contrast-enhanced computed tomography (CT) and fluorine 18 fluorodeoxyglucose PET/CT (18F FDG PET/CT) showed similar results. Subsequently, the patient underwent a right radical nephrectomy, but histopathological examination revealed XGP with ADPKD. On the follow-up, the patient\'s symptoms were relieved.
CONCLUSIONS: XGP should be kept in mind during the differential diagnosis of renal masses with ADPKD even in the absence of characteristic clinical symptoms and imaging manifestations.
方法:这里,我们报告了一例66岁的女性,有双侧ADPKD和尿路感染的病史,由于右侧腹部疼痛入院。虚弱,低烧。超声造影显示右肾恶性肿块,怀疑是多囊性肾细胞癌。此外,对比增强计算机断层扫描(CT)和氟18氟脱氧葡萄糖PET/CT(18FFDGPET/CT)显示相似的结果。随后,患者接受了右肾根治性切除术,但组织病理学检查显示XGP伴ADPKD。关于后续行动,病人的症状缓解了。
结论:在肾脏肿块伴ADPKD的鉴别诊断中,即使没有特征性的临床症状和影像学表现,也应牢记XGP。
